Top 7 Underrated Inventions of the 21st Century

3D Bioprinting

3D bioprinting involves using cells to print living tissues and eventually organs. Layer by layer, biocompatible materials and cells are deposited to form functional living systems. This technology could revolutionize organ transplants and drug testing. Instead of waiting for donor organs, hospitals could potentially print customized organs. Although often eclipsed by traditional 3D printing, 3D bioprinting holds life-saving potential. While still in early stages, rapid advancements hint at a promising future.
